Ye shall not therefore oppress one another,.... By over or underrating estates:
but thou shalt fear thy God; and the fear of God being before their eyes, and on their hearts, would preserve both buyer and seller from doing an ill thing, when it was in the power of either, through the necessity of the one, or the ignorance of the other, see Nehemiah 5:15,
for I am the Lord your God; omniscient, and knows all that is done in the most private and artful manner; and omnipotent and able to punish both, which of them either should oppress or defraud, see 1-Thessalonians 4:6.

Ye shall not oppress one another, but thou shalt fear thy God--This, which is the same as Leviticus 25:14, related to the sale or purchase of possessions and the duty of paying an honest and equitable regard, on both sides, to the limited period during which the bargain could stand. The object of the legislator was, as far as possible, to maintain the original order of families, and an equality of condition among the people.
